Specification forming part of Letters Patent No. 123,826, dated February 20, 1872.

Specification describing a certain Improved Stop-Motion for Drawing-Frames, invented by DANIEL W. HAYDEN, of Wauregan, in the county of Windham and State ofConnect- -is applied without any alteration of the ordinarycatch-lever or otherparts commonly used 5 and it consists of only one piece and the attaching bracket, which can be made and applied at a triiiing cost, and works. with such freedom as to be very sensitive and efficient.

Figure l is a longitudinal sectional elevation of my improved stop-motion, and Fig. 2 is a top view partly in plan and partly in section.

A represents the callender-rollers; B, the trumpet; O, the arm on which-it is mounted; D, the weighted catch-arm, which, together with arm C, being both pivoted at E and \O, having a shoulder at F bearing on a toe of D, constitute the weighted catch-lever commonly used in connection with the stop-wheel 'G for throwingthe belt off when the sliver77 or end breaks. Now, for also throwing off the belt in case a knot, bunch, snarl, or other defect on the sliver occurs which it is desirable to arrest and remove, I combine the elbowweighted catch-lever H I with said arm D and the wheel G, as shown, so that the eleva-tion of the free end of arm D above the normal position, which will take place whenever there is any undue strain on the trumpet by reason of a knot or the like choking in it, will throw up part I and swing catch part H forward against the stop-wheel G to engage and hold it, and cause it to throw off the belt in the same manner that it does when arrested by arm D. I arrange the weighted part I of this catch-lever and the part of arm D working with it, so as to prevent arm D from rising high enough by the friction of the sliver on the trumpet when working regularly to4 cause the catch H to engage the wheel G, which is accomplished by having the weight of arm I in excess of the strain of the sliver and supporting it in a horizontal position by the stop J ready to be lifted quickly by the end when the choking takes place. This may, however, be regulated to a considerable extent by the adjustable weight K on arm D, which may be put on arm l, if preferred, or it may be dispensed with altogether. In this example I have represented a forked bracket, L, bolted to the cross-piece M for supporting the pivot N on which the catch I H is suspended, and this is all I have to provide for attaching it, for the cross-bar M and the posts O for snpporting it are used on drawil'ig-iranies for supporting the stop-motion employed for stopping when the cans become empty.

Of course other contrivances for supporting it may be used, if preferred. It will be seen that the catch-lever H I performs two important function s-viz., holdin g the trumpet in the regular working position, and stopping the machine when the trumpet is choked.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In stop-motions for drawin g-frames the combination of lever H I J with the trumpet-lever C D, wheel G, and bracket L, when all are constructed and arranged substantially as and for the purpose described. y

. The above specification of my invention signed by me this 27 th day of October, 187i.
